Summary

P315 proposes to provide further transparency on Suppliers’ Meter Volume and MPAN counts.

To help all Parties understand the gross Supplier market shares, the volumes will exclude embedded generation and will be broken down by Market Participant ID (MPID), customer type, Active Export (AE)/Active Import (AI) and Half Hourly/Non Half Hourly.

Some market level consumption data will also be made available to a wider range of market participants.

The Modification and its Initial Written Assessment were presented to the BSC Panel at its meeting on 9 October 2014.

The P315 Assessment Report was initially presented to the Panel on 9 April 2015, but the Modification was sent back for further assessment. Over the P315 Assessment Procedure an impact assessment and three consultations on P315 were issued to industry participants.

The P315 Assessment Report was finally presented to the Panel on 13 August 2015, and the Workgroup recommended to the BSC Panel that the Alternative Modification should be approved. After consulting on its initial views, the BSC Panel recommended at its meeting on 10 September 2015 that the Alternative Modification should be approved.
